From Jim Lance: "Some months ago I had the good fortune to be included in a Scripps
Institution of Oceanography expedition to Islas Reviliagigedos — west Mexico's only oceanic
island chain. This volcanic group, about 1500 km south of San Diego and 600 km west of
mainland Mexico, consists of four principal islands with one, S.in Benedicto, having blown its
OPISTHOBMANCH NEMSLETTER Volume 13, Number 6, Page 22
top about 30 years ago and remaining almost totally barren to this day.
Our ship, the Alpha Helix, was until recently the flag vessel of the Scripps research fleet
and was well equipped for investigations at sea. Althought our program was primarily oriented
toward the collecting of algae and invertebrates for natural products chemistry research, ray
14 collector /colleagues aboard were very cooperative in extending their activilies to help in a
survey of the opistnobranch population from these and the more inshore Tres Marias Islands.
Although we circled the islands from seaward, it was evident from observation, charts and
enormous surf that intertidal or inshore collecting wouldn't prove feasible. Thus, most of our
work was confined to offshore snorkel and SCUBA. In all, I was able to record only a rather
disappointing 21 species consisting of 123 specimens. Still, 5 of those are undescribed and
one, an elysoid sacoglossan. probably represents a new genus with affinites to both Caribbean
and Indo-Pacific relatives." - Jim Lance.
From Bob Burn: "The first two weeks of April, I spent with Fred Wells of the Western
Australian Museum. Six days were taken up with field work in the Albany area of southern
Western Australia, where we collected on soft bottoms, among seagrasses and on reef platforms
with satisfying results. Albany is situated on King George Sound, an area visited and collected
by Quoy and Gaimard in October 1826. These Frenchmen described several bubble shells from
that locality — namely Liloa brevis, Akera bicincta, Adamnestia arachis and Bulla australis
(now B. quoyii Gray). We were fortunate enough to find all except the third species. Tornatina
apicluata Take also has its type locality in King George Sound, and a number of living
specimens were found.
Two range extensions are worth mentioning. Aplysia ^i^antea Sowerby 1869 was found 400 km
further south and east than normal, and Crimora multidigitalis Burn 1957 was found 2500 km
further west than previously reported." - Bob Burn.
From Kikutaro Baba: "In March I visited New Zealand and Sydney for a short time.
Fortunately I was able to speak with Dr. M.C. Miller of the Auckland University at his residence,
and Dr. R.W. Rudman of the Australian Museum at his office.
In May I tried again to study Melibe of Japan rather extensively. Possibly the most common
form of our Melibe is referable to Melibe pilosa Pease, i860 in its wide sense, as some of the
previous authors suggested. The types of M. papillosa (de Filippi, 1867) and M. vexillifera
Bergh, 1880 seemed to be based both on juvenile specimens of M. pilosa Pease, i860 (s.l.). It is
hoped, however, that the pilosa specimens from Hawaii will be studied in more detail by the
local workers." - Kikutaro Baba
The Los Angeles Oceanic Society's Coastal Monitoring Conference, Seasons in the Sea, will
held Saturday, June 13, 1981, at the Chace Park Community Building, Mindanao Way, Marina Del Rey,
California. Several papers on marine life and marine features will be given. One paper by
John Scotesi is entitled: Sea Hare Migration Phenomenon off Palos Verdes. Conference pre-
registration is $3.00 per person.
The fourteenth annual meeting of the Western Society of Malacologists will be held from June
23, 1981, to June 26, 1981, at San Diego State University. Olmeca Hall will be the focal point for
housing and some of the evening small gatherings. The actual meetings will be in Aztec Center

I apologize for the delay in publishing this
issue of Opisthobranch Newsletter. I have been
working for several months to complete an index
for publication in the ON and have decided that it
should be printed in draft form so that people can
start using it and, hopefully, send additions and
corrections. The wait should be worthwhile.

Range Extensions of Several Opisthobranchs
from Humboldt County, California
Recent publications (Behrens, 198O; McDonald
and Nybakken, 19o1 ) have contributed signifi-
cantly to our knowledge of the biology of
opisthobranch molluscs from the Northeast
Pacific. However, because of the paucity of
published accounts from northern California and
Oregon, the zoogeographioal information within
these works is, in several cases, inaccurate.
Historically, studies of opisthobranch molluscs
have centered around two geographical regions:
from Boaega Bay, California to Baja California,
Mexico, and from nortnwest Washington to
northwest British Columbia, Canada. The reported
distributions of the species present in the
littoral zone reflect the intensity of study in
these regions. Unfortunately, few data are
available from the area between these two
regions. This paper presents new distributional
data for ten n'udibranch species from Humboldt
County, California (figure 1).
